Description

The Arista 7812R4 is a high-density 12-slot modular data centre switch chassis designed for hyperscale spine and core deployments demanding massive throughput and carrier-grade resiliency. This DC-powered bundle ships fully configured with a 7812 chassis, 10x 3kW DC power supplies (N+N redundancy), 5x FM-R4 fabric modules, 1x fabric card module (FCM), and 1x 7800-Sup1A supervisor — plus an extended rack kit — providing everything required for an immediate production-ready installation. The Arista EOS operating system delivers a consistent, programmable network OS with deep telemetry, streaming analytics, and zero-touch provisioning across the entire 7800 Series platform.

The 7812R4 fabric architecture supports multi-terabit switching capacity with deterministic low-latency forwarding, making it the platform of choice for financial services, cloud providers, and large enterprise data centres requiring non-blocking performance at scale. The included Sup1A supervisor provides full in-service software upgrades (ISSU) and stateful switchover (SSO) for continuous availability.
